The last time that I fitted a gas ram (on a BSA) it was, as I recall, a simple spring out gas ram in job. The instructions for my Vulcan are telling me to cut down part of the body end plug that acts as a mount for the spring guide. If I do this it means that it will be difficult to return the Vulcan to spring power at some point in the future. I'm reluctant to butcher the rifle and would rather cut or grind the end of the rod on the gas ram to the required length. Has anybody done this? Are there issues that I haven't considered?

I'm a bit miffed at the need to do anything. It's sold as a fitment for the Vulcan and yet there is a need to modify the gun and the ram itself is a very loose fit inside the piston and the advice there is to wrap it in insulating tape until it's a good fit. I can only imagine the sticky mess that this will end up as. Lesson learned, won't be getting another.
